Earthquake Network

About this app

Earthquake Network is the most comprehensive app on earthquakes and for most world countries it is the only earthquake early warning system for receiving real time alerts. Earthquake Network gives you: - Real time alerts if you live close to the epicentre - Alerts seconds in advances if you live far from the epicentre - Real time user reports on felt earthquakes - Free earthquake data from 21 seismic networks including U.S., Puerto Rico, India, Indonesia, Turkey, Mexico, Chile, Peru, Ecuador, Argentina, Venezuela, Dominican Republic, Colombia, Costa Rica, Nicaragua, China, New Zeland, Japan, Italy, Croatia, Spain and Greece The Earthquake Network research project (https://www.sismo.app) aims at developing a smartphone-based earthquake early warning system able to detect earthquakes in real time and to alert the population in advance. Smartphones are able to detect earthquakes thanks to the accelerometer on-board each device. When an earthquake is detected, users with the application installed are immediatly alerted. Since earthquake waves travel at around 5 km/s it is possible to alert the population not yet reached by the damaging waves of the earthquake. For the scientific details about the project please refer to the scientific paper on Frontiers at https://bit.ly/2C8B5HI Subscriptions: When an earthquake is detected in real time by smartphones near the epicenter, the server sends an alert to all users with the app. Alerting all users can take up to 10 seconds since it is not technically feasible to do so instantly. Now you can join the priority lists of the first 10,000 or 100,000 people alerted in real time.
